pt(Percona Toolkit)工具安装
一．pt(Percona Toolkit)工具是由Percona公司开发的一个用perl语言编写的工具集,包含很多功能,例如在线更改数据表结构,校验主从数据,检查数据库状态,分析慢查询等这些靠人手做起来比较麻烦的事情,功能强大,操作简单
二.安装依赖包
yum install -y perl perl-IO-Socket-SSL perl-DBD-MySQL perl-Time-HiRes perl-Digest-MD5 perl-ExtUtils-MakeMaker
下载Percona Toolkit工具编译包
[root@node1 ~]# wget "https://www.percona.com/downloads/percona-toolkit/3.0.3/binary/tarball/percona-toolkit-3.0.3_x86_64.tar.gz"
解压
[root@node1 ~]# tar xf percona-toolkit-3.0.3_x86_64.tar.gz
进入目录安装
[root@node1 ~]# cd percona-toolkit-3.0.3
开始编译安装
[root@node1 percona-toolkit-3.0.3]# perl Makefile.PL
[root@node1 percona-toolkit-3.0.3]# make
[root@node1 percona-toolkit-3.0.3]# make install
就显示出一些常用的pt命令

搞个测试，MySQL服务状态显示：
[root@node1 ~]# pt-mysql-summary --user=root --password='abc123'
